Theorycraft

The best secondary Specialization in Zero Company

Scout, for most Operators. A dual-class build is limited by the shared Advantage pool rather than by damage, and the Scout is the only class that fills it on purpose — so it makes the Operator's own second class affordable. Scoundrel is the better pick on anything that attacks often, and Medic is what permadeath argues for.

This has not been tested against the retail game

Zero Company released on 27 August 2026. The rules cited below are sourced and dated, and assembling them into a recommendation is reasoning rather than measurement — so this page is theorycraft and stays labelled that way until it has been played. The unlock point itself is a single previewer’s spoken figure, and whether every primary-secondary combination is even legal has not been confirmed by anybody.

Why this question is not the tier list again

The class tier list ranks the eight for a squad slot, fully invested. The best starting class asks which to take at rank one with nothing unlocked. Neither answers this one, because a secondary is not competing for a bay — it is competing for Focus Points and Advantage on an Operator who already has a job.

That changes the answer completely. A class that is mediocre in its own right can be the best possible secondary if it supplies something the primary cannot buy, and the strongest class on the tier list can be a poor secondary if it wants the same resource the primary already spends. The pool holds ten for the entire squad and starts every fight empty, which is the constraint everything below is argued from.

The unlock arrives after Cycle 18, roughly halfway through the campaign. That number spent three weeks here as one previewer’s remark; two launch-week guides of the shipped game now print it independently, and one of them says it lands for the whole roster at once. Until then this is a decision to plan rather than to make, and the Squad Builder keeps the second slot visibly locked for the same reason.

One of those guides adds a caveat no other source repeats: that a secondary’s Focus Tree ranks stop at Tier 5 where a primary’s reach Tier 6. It is single-publisher and is not treated here as a rule, but it costs nothing to act on while it stands. Where a pair could go either way, put the class whose last rank you actually want in the primary slot — the sixth is where several ladders buy a behaviour rather than a number.

The recommendation

Four secondaries, in order

Each answers a different primary. Every case names what argues against it.

  1. 1

    Scout

    The default second classTheorycraft

    It is the only Specialization that pays for the rest of the squad rather than for itself, and a secondary is where that costs you least. Advantage is earned one point at a time by damaging enemies, caps at ten, and starts every fight empty — so the binding constraint on a dual-class Operator is almost never damage, it is whether anything they gained is affordable. Adding Scout to an Operator who already attacks often turns their ordinary turn into pool generation, and Spotted removes distance and smoke hit-chance penalties from a marked target for everybody. Given to an Operator whose primary is a spender, it makes their own second class affordable.

    Against it It adds no damage of its own, so on an Operator you wanted to hit harder it will feel like nothing happened. If the squad already contains a dedicated Scout, this is the one pick on the list that genuinely duplicates.

  2. 2

    Scoundrel

    The best pick on an attackerTheorycraft

    The only confirmed counter to flat Defense, and Defense is subtracted per hit rather than per turn — so armour penetration is worth most to whoever attacks most often, which is exactly the kind of Operator that already has a primary worth keeping. Four points ignored plus Identify Weakness turning the next attack into a guaranteed critical means the secondary supplies what almost no primary does: a multiplier rather than more of the same. On a Gunslinger primary stacking Onslaught, or on Cly Kullervo after her jetpack lands her next to something, it compounds instead of overlapping.

    Against it The kit is thin until invested, and Focus Points spent on a secondary are Focus Points not spent finishing the primary's ladder. It is also the pick most likely to be wasted if the squad already runs a Scoundrel handing out Vulnerable.

  3. 3

    Medic

    The pick permadeath argues forTheorycraft

    Three Injuries mean permanent death on standard difficulty, and an Injury is taken on being reduced to zero health — so healing is not a comfort mechanic here, it is the thing standing between a bad turn and losing an Operator and every Bond they held. As a secondary it is unusually efficient, because the Medic's value does not scale with how much of the turn it gets: one application is one application whether the Operator is a Medic or a Medic second. On a Beskar Mode run, where you cannot reload past the loss, this is the pick.

    Against it It is the least interesting choice on the list and it is bought with the same Focus Points as the exciting ones. If the squad already contains a Medic, a second one is genuinely redundant rather than merely overlapping.

  4. 4

    Heavy

    For the Operator who is already in frontTheorycraft

    Heavy Armor Training's +2 Defense subtracts flatly from every hit taken, which makes it a secondary that improves an Operator's worst turn rather than their best one. It is the natural addition to anything whose primary already puts it in the open — a melee Soldier, or Cly Kullervo, whose Talent lands her in the middle of the group she just scattered and who already carries +3 Defense from Mandalorian armour. Intimidating Posture also makes the primary blaster attack taunt, so target selection costs no separate action.

    Against it Taunting concentrates fire by design, which is a strange thing to add to an Operator you did not build to absorb it. On anything fragile this is worse than not taking it.

The rule

Four pairings the shared pool makes expensive

Not prohibitions — nothing states that any combination is illegal. These are the ones that cost more than they return.

  • Two Advantage-hungry classes on one Operator. Every Specialization has an Advantage Ultimate and the pool holds ten for the whole squad, so a dual-class Operator with two expensive abilities is an Operator who fires one of them and owns the other on paper.
  • A secondary that repeats what the primary already does. Two sources of single-target damage on one body is one Operator's worth of turns either way — the four bays are the constraint, not the classes.
  • A secondary that duplicates another squad member's job. Spotted, Vulnerable and a taunt are all squad-wide effects; a second copy adds far less than the first did.
  • Spending the whole Focus budget on the new class. The primary's ladder is where most published upgrade values live, and several classes are ranked far apart at rank one and rank five.

The one Operator this is a real decision for

Cly Kullervo is locked to the Mandalorian Warrior exotic class and can still add any of the eight as a secondary — the only Operator in the game who is both. For everyone else the second Specialization is an addition to a class they chose; for her it is the only Specialization she will ever have, which makes it a substantially larger decision.

Tel-Rea Vokoss is the opposite case and the reason the distinction is worth drawing at all. She is locked out of the eight entirely, even as a secondary, and invests in three abilities of her own instead. Being locked to an exotic class and being locked out of a second class are different restrictions, and only one of them applies to Cly.
